After extracting data from the (read-only) chip in a legitimate passport, he placed a version of the data with an altered passport photo (JPEG2000 is used in these chips) into a writable chip. The altered photo created a buffer overflow in two RFID readers he tested, causing both to crash. Grunwald suggests that vendors are typically using off-the-shelf JPEG2000 libraries, which would make the vulnerability common."
